How to Find the Perfect T-Shirt Size | Complete Fit Guide
Why T-Shirt Sizing Matters
Finding the perfect t-shirt size isn’t just about small, medium, or large—it’s about fit, comfort, and confidence.
Whether you're buying custom t-shirts, graphic tees, or ordering for a group, the right size ensures:
Comfortable everyday wear
A flattering fit for your body type
Better-looking printed designs
Fewer returns or exchanges
At Mustang Canyon Outfitters, every shirt is made-to-order—so choosing the right size upfront is key.
Step 1: Measure a Shirt You Already Love
The easiest way to find your perfect fit is to measure a shirt you already own.
What You’ll Need:
A flat surface
A measuring tape
Key Measurements:
1. Chest Width (Most Important)Lay the shirt flat and measure across from armpit to armpit.
2. Shirt LengthMeasure from the top of the shoulder down to the bottom hem.
3. Sleeve Length (Optional)Measure from shoulder seam to sleeve end.
Compare these numbers to the size chart before ordering.
Step 2: Use a T-Shirt Size Chart
While sizes can vary slightly, most standard tees (like Gildan and similar brands) follow a consistent structure.
Example General Size Guide:
Size | Chest Width (inches) | Length (inches) |
Small | 18–19 | 28 |
Medium | 20–21 | 29 |
Large | 22–23 | 30 |
XL | 24–25 | 31 |
2XL | 26–27 | 32 |
Pro Tip: If you're between sizes, consider how you like your shirts to fit (see next section).
Step 3: Choose Your Preferred Fit Style
Not all customers want the same fit. Here’s how to decide:
Standard Fit (Most Popular)
Classic, comfortable fit
Not too tight, not too loose
Best for everyday wear and most customers.
Athletic / Slim Fit
More fitted around chest and arms
Tapered look
👉 Consider sizing up if you prefer extra room
Relaxed / Loose Fit
Extra room throughout
More laid-back feel
👉 Great for casual or oversized style
Avoid these common issues:
❌ Guessing your size without measuring
❌ Assuming all brands fit the same
❌ Forgetting shrinkage (especially cotton)
❌ Ordering too small for a tighter look
👉 When in doubt, size up for comfort.
Sizing Tips for Printed & Graphic T-Shirts
For bold graphic designs (like yours), sizing matters even more.
Larger sizes = bigger print area
Better fit = better design placement
Too tight = design may stretch/distort
👉 A properly fitted shirt makes your design look clean, sharp, and professional.
Will My Shirt Shrink?
100% Cotton: May shrink slightly if dried on high heat
Blends: Minimal shrinkage
Polyester: Rarely shrinks
👉 To be safe:
Wash cold
Dry low heat or air dry
